# COTH

COTH(number)

Returns the hyperbolic cotangent of a number.

 number The angle.

 REMARKS
 * This function was added in Excel 2013.* The hyperbolic cotangent of a number is 1/TANH.* The hyperbolic arctangent of a number is the inverse of the TANH.* If Abs(number) > 2^27, then #NUM is returned.* If "number" is not numeric, then #VALUE is returned.* You can use the TANH function to return the hyperbolic tangent.* You can use the SECH function to return the hyperbolic secant.* You can use the CSCH function to return the hyperbolic cosecant.* You can use the ACOTH function to return the hyperbolic arc-cotangent.* For a working example refer to the Quant > Hyperbolic Functions page.* For the Microsoft documentation refer to support.microsoft.com* For the Google documentation refer to support.google.com
